[0021] Beneficial effects of the present invention:

[0022] 1. By setting a sliding base plate and a rotating cylinder, when the CNC bending equipment uses the mold to bend metal materials, the use of the lower mold body and the upper mold body is optimized, and the position adjustment of the lower mold body and the upper mold body can be completed by moving and rotating, so as to quickly complete the adjustment operation of the bending mold, so that it can be flexibly applied to bending processing of different structures;

[0023] During operation, the lower mold body adopts a movable structure for adjustment operation, and the upper mold body adopts a rotating structure for adjustment operation. When performing bending operations of different structures, the rotation adjustment of the upper mold body and the movement adjustment of the lower mold body are used to quickly adjust the positions of the upper mold body and the lower mold body, so that the upper mold body and the lower mold body are used in coordination. By moving the upper mold body downward, the metal material is bent between the upper mold body and the lower mold body. When the upper mold body is in use, the gear is driven by the driving motor to drive the rotating cylinder to rotate. The rotating cylinder can drive several groups of upper mold bodies to rotate, thereby adjusting the use position of the upper mold body, so that the upper mold body required to be used remains in a vertical downward state. When the rotating cylinder rotates to the corresponding position, the limit card is used The two pins of the seat can assist in fixing one end of the rotating cylinder. The pin is driven by an electric structure so that the pin is inserted into the docking slot of the rotating cylinder to complete the auxiliary fixation of the rotating cylinder and improve the stability of the rotating cylinder during the downward pressing and bending operation. When the lower mold body is in use, the motor is used to drive the lead screw so that the lead screw can use the threaded structure to drive the sliding base plate to move horizontally. The sliding base plate can drive several groups of lower mold bodies to move horizontally, thereby adjusting the use position of the lower mold body, and making the lower mold body and the upper mold body correspond to each other up and down. The metal material is placed between the lower mold body and the upper mold body by using a loader, and the lifting base plate is driven by a hydraulic rod so that the lifting base plate can drive the upper mold body to move up and down, and cooperate with the setting of the lower mold body to complete the shaping and bending of the metal material.

[0024] 2. By setting up a feeder, when the quick-adjusting bending mold and its CNC bending equipment are used, the use of the sliding base plate and the rotating cylinder is optimized, so that the metal material can be accurately placed between the lower mold body and the upper mold body to avoid tilting and improve the bending effect;

[0025] When in use, first place the metal material inside the mobile material frame, use the first clamping plate and the second clamping plate to limit the two ends of the metal material in the mobile material frame, slide and adjust the positions of the first clamping plate and the second clamping plate according to the length of the metal material, and then use the fixed side rod in conjunction with the telescopic clamping rod to limit and fix the two sides of the metal material. During operation, the fixed side rod is pushed according to the width of the metal material so that the telescopic clamping rod at one end of the fixed side rod abuts against the side of the metal material. The telescopic clamping rod is controlled by the motor through the threaded bolt. When the metal material is put in, the mobile material frame is pushed so that the mobile material frame moves out from the upper end of the mobile pallet, so that the bottom of the mobile pallet is in an open state. At this time, the controller is used to start the motor inside the fixed side rod so that the motor drives the threaded bolt to rotate, and the threaded structure on the surface of the threaded bolt is used to adjust the use length of the telescopic clamping rod so that the telescopic clamping rod is separated from the two sides of the metal material, so that the metal material falls from the inside of the mobile material frame. The first clamping plate, the second clamping plate and the fixed side rod are used to limit and fix the metal material to the mold structure, thereby improving the accuracy of the feeding operation and avoiding bending and tilting.

[0026] 3. By setting the docking card strip and the bar card slot, in the quick-adjusting bending mold and its CNC bending equipment, with the use of the card slot structure, the lower mold body and the upper mold body can be flexibly replaced;

[0027] During operation, the sliding base plate can use its upper end slot structure to complete the installation and fixation of the lower mold body. Secondly, the use of the strip slot and the docking card strip can realize the splicing and fixation between the upper mold body and the rotating cylinder. Several groups of upper mold bodies and lower mold bodies can be installed on the rotating cylinder and the sliding base plate. The flexibility of the use of the upper mold body and the lower mold body is improved by flexible replacement. BRIEF DESCRIPTION OF THE DRAWINGS

The upper mold body 4 is movably installed above the lower mold body 3. The number of lower mold bodies 3 and upper mold bodies 4 is four groups. The four groups of lower mold bodies 3 are connected and fixed by sliding base plates 2, and the four groups of upper mold bodies 4 are connected and fixed by rotating cylinders 6. The four groups of lower mold bodies 3 and sliding base plates 2 are all spliced ​​and fixed by card grooves, and the four groups of upper mold bodies 4 and rotating cylinders 6 are all spliced ​​and fixed by docking card strips 5. The lower end of the sliding base plate 2 is driven by a screw rod 1.

[0038] like Figure 2 As shown, a CNC bending equipment for a bending mold includes a fixed base 7 and a lifting base 9. The lifting base 9 is movably installed at the inner upper position of the fixed base 7. The lifting base 9 and the fixed base 7 are movably connected through four guide rods 12. A plurality of groups of upper mold bodies 4 are movably installed on the inner side of the lifting base 9. A plurality of groups of lower mold bodies 3 are arranged on the inner side of the fixed base 7 below the lifting base 9. The lower mold bodies 3 are adjusted by a movable structure, while the upper mold body 4 is adjusted by a rotating structure. When performing bending operations of different structures, the upper mold body 4 is rotated and adjusted, and the lower mold body 3 is moved and adjusted, so that the upper mold body 4 and the lower mold body 3 are quickly adjusted, so that the upper mold body 4 and the lower mold body 3 are used in coordination, and the metal material is bent between the upper mold body 4 and the lower mold body 3 by moving the upper mold body 4 downward.

[0039] To solve the problem of rapid replacement of bending dies, such as Figure 3 and 4 As shown, several groups of upper mold bodies 4 and lifting base plates 9 are movably connected through a rotating cylinder 6, and the upper mold bodies 4 are spliced ​​and installed on the outer surface of the rotating cylinder 6, and several groups of lower mold bodies 3 and fixed bases 7 are movably connected through a sliding base plate 2, and several groups of lower mold bodies 3 are spliced ​​and installed on the upper outer surface of the sliding base plate 2. A bending groove 20 is provided inside the lower mold body 3. Several groups of upper mold bodies 4 can be driven to rotate by the rotating cylinder 6, so as to adjust the use position of the upper mold body 4. Secondly, the sliding base plate 2 can be used to drive several groups of lower mold bodies 3 to move horizontally, so as to adjust the use position of the lower mold body 3. Secondly, the upper mold body 4 and the lower mold body 3 both adopt a splicing structure design, so that the upper mold body 4 and the lower mold body 3 can be flexibly installed and fixed.

[0040] like Figure 3As shown, the outer surface of the rotating cylinder 6 is provided with a strip groove 16 used in conjunction with the upper mold body 4, and the upper mold body 4 and the strip groove 16 are fixed by docking with the docking strip 5. A driving motor 8 is provided at one end of the rotating cylinder 6. The driving motor 8 can drive the rotating cylinder 6 through the gear 15 structure, so that the rotating cylinder 6 can rotate to adjust the position of the upper mold body 4. Secondly, the use of the strip groove 16 in conjunction with the docking strip 5 can realize the splicing and fixation between the upper mold body 4 and the rotating cylinder 6.

[0041] The rotating cylinder 6 and the driving motor 8 are driven by a gear 15. A limiting clamp 17 is installed at the other end of the rotating cylinder 6. Two pins 19 are movably installed at the end of the limiting clamp 17. A docking slot 18 is provided on the outer surface of one end of the limiting clamp 17. When the rotating cylinder 6 rotates to the corresponding position, the two pins 19 of the limiting clamp 17 can be used to assist in fixing one end of the rotating cylinder 6. The pin 19 is driven by an electric structure so that the pin 19 is inserted into the docking slot 18 of the rotating cylinder 6, thereby completing the auxiliary fixation of the rotating cylinder 6 and improving the stability of the rotating cylinder 6 during the downward pressing and bending operation.

[0042] like Figure 4 As shown, the lower end of the sliding substrate 2 is driven by the screw rod 1, and the outer surface of the upper end of the sliding substrate 2 is provided with a slot for cooperating with the lower mold body 3. The screw rod 1 is driven by a motor, so that the screw rod 1 can drive the sliding substrate 2 to translate using a threaded structure. Secondly, the slot structure can complete the splicing and fixation between the sliding substrate 2 and the lower mold body 3.

[0043] A storage tray 13 is fixedly mounted on the front end outer surface of the fixed base 7, and a loader 14 is movably mounted on the upper end of the storage tray 13. The loader 14 includes a movable support plate 21 and a movable material frame 27. The movable material frame 27 is movably mounted on the upper end outer surface of the movable support plate 21. By using the loader 14, the loading operation of the metal material can be completed by moving the movable material frame 27 on the movable support plate 21, so that the metal material is placed between the lower mold body 3 and the upper mold body 4.

[0044] To solve the problem of feeding the bending die, such as Figure 5 and 6 As shown, the first clamp plate 24 and the second clamp plate 26 are movably installed on the inner side of the movable material frame 27, and the first clamp plate 24 and the second clamp plate 26 are arranged side by side. The first clamp plate 24 and the movable material frame 27 as well as the second clamp plate 26 and the movable material frame 27 are movably connected through the clamping grooves. The first clamp plate 24 and the second clamp plate 26 can be used to limit the two ends of the metal material in the movable material frame 27, and the positions of the first clamp plate 24 and the second clamp plate 26 can be arbitrarily adjusted according to the length of the metal material.

[0045] Fixed side rods 25 are provided on both sides of the movable material frame 27, and a telescopic clamping rod 28 is movably installed at one end of the fixed side rod 25. The fixed side rod 25 and the movable material frame 27 are locked and fixed by a fastening bolt 11. The fixed side rod 25 is used in conjunction with the telescopic clamping rod 28 to limit and fix the two sides of the metal material.

[0046] A threaded bolt 29 is provided between the fixed side rod 25 and the telescopic clamping rod 28. The fixed base 7 and the lifting base plate 9 are driven by a hydraulic rod 10. A push-pull handle 23 is provided at the end of the movable material frame 27. A controller 22 is fixedly installed on the outer surface of the push-pull handle 23. The lifting base plate 9 is driven by the hydraulic rod 10, so that the lifting base plate 9 can drive the upper mold body 4 to move up and down, and cooperate with the setting of the lower mold body 3 to complete the shaping and bending of the metal material.

[0047] When in use, traditional CNC bending equipment adopts a single mold structure design, so that it can only complete one shape of bending operation when in use. When performing different types of bending operations, it is impossible to quickly adjust the mold structure, which reduces its flexibility during bending processing operations;

[0048] To this end, by setting the sliding base plate 2 and the rotating cylinder 6, when the CNC bending equipment uses the mold to perform the bending operation of the metal material, the use of the lower mold body 3 and the upper mold body 4 is optimized, and the position adjustment of the lower mold body 3 and the upper mold body 4 can be completed by moving and rotating, so as to quickly complete the adjustment operation of the bending mold, so that it can be flexibly applied to the bending processing of different structures;

[0049] During operation, the lower mold body 3 adopts a movable structure for adjustment operation, and the upper mold body 4 adopts a rotating structure for adjustment operation. When performing bending operations of different structures, the rotation adjustment of the upper mold body 4 and the movement adjustment of the lower mold body 3 are used to quickly adjust the positions of the upper mold body 4 and the lower mold body 3, so that the upper mold body 4 and the lower mold body 3 are used in coordination with each other. By moving the upper mold body 4 downward, the metal material is bent between the upper mold body 4 and the lower mold body 3. When the upper mold body 4 is in use, the gear 15 is driven by the driving motor 8, so that the gear 15 drives the rotating cylinder 6 to rotate. The rotating cylinder 6 can drive several groups of upper mold bodies 4 to rotate, thereby adjusting the use position of the upper mold body 4, so that the upper mold body 4 required to be used remains in a vertical downward state. When the rotating cylinder 6 rotates to the corresponding position, the two ends of the limit clamp 17 are used The root latch 19 can assist in fixing one end of the rotating cylinder 6. The latch 19 is driven by an electric structure so that the latch 19 is inserted into the docking slot 18 of the rotating cylinder 6 to complete the auxiliary fixation of the rotating cylinder 6 and improve the stability of the rotating cylinder 6 during the downward bending operation. When the lower mold body 3 is in use, the motor drives the screw rod 1 so that the screw rod 1 can drive the sliding base plate 2 to translate using the threaded structure. The sliding base plate 2 can drive several groups of lower mold bodies 3 to move horizontally, thereby adjusting the use position of the lower mold body 3, and making the lower mold body 3 and the upper mold body 4 correspond to each other up and down. The metal material is placed between the lower mold body 3 and the upper mold body 4 by using the feeder 14, and the lifting base plate 9 is driven by the hydraulic rod 10 so that the lifting base plate 9 can drive the upper mold body 4 to move up and down, and cooperate with the setting of the lower mold body 3 to complete the shaping and bending of the metal material.

[0050] Secondly, when CNC bending equipment is performing metal material bending operations, the loading of metal materials needs to be done manually, which reduces its continuous bending efficiency. In addition, manual loading is prone to tilting, which reduces the bending yield of metal materials and has a single functionality.

[0051] To this end, by setting a feeder 14, when the fast-adjustable bending mold and its CNC bending equipment are used, the use of the sliding base plate 2 and the rotating cylinder 6 is optimized, so that the metal material can be accurately placed between the lower mold body 3 and the upper mold body 4, avoiding the tilting phenomenon and improving the bending effect;

[0052] When in use, first place the metal material inside the mobile material frame 27, and use the first clamping plate 24 and the second clamping plate 26 to limit the two ends of the metal material in the mobile material frame 27. Sliding and adjusting the positions of the first clamping plate 24 and the second clamping plate 26 according to the length of the metal material, and then using the fixed side rod 25 in conjunction with the telescopic clamping rod 28, the two sides of the metal material can be limited and fixed. During operation, the fixed side rod 25 is pushed according to the width of the metal material, so that the telescopic clamping rod 28 at one end of the fixed side rod 25 abuts against the side of the metal material. The telescopic clamping rod 28 is controlled by the motor through the threaded bolt 29, and the mobile material frame is pushed during the metal material delivery operation. 27, so that the mobile material frame 27 is moved out from the upper end of the mobile support plate 21, so that the bottom of the mobile support plate 21 is in an open state, at this time, the controller 22 is used to start the motor inside the fixed side rod 25, so that the motor drives the threaded bolt 29 to rotate, and the threaded structure on the surface of the threaded bolt 29 is used to adjust the use length of the telescopic clamping rod 28, so that the telescopic clamping rod 28 is separated from the two sides of the metal material, so that the metal material falls from the inside of the mobile material frame 27, and the first clamping plate 24, the second clamping plate 26 and the fixed side rod 25 are fixed to the limit position, so that the metal material is accurately docked with the mold structure, thereby improving the accuracy of its feeding operation and avoiding bending and tilting;

[0053] At the same time, the mold structure of the traditional CNC bending equipment does not have a quick replacement structure, and the replacement operation of the upper and lower mold structures of the CNC bending equipment cannot be completed quickly, which reduces its use effect;

[0054] To this end, by providing the docking card strip 5 and the bar card slot 16, in the fast-adjustable bending mold and its CNC bending equipment, with the use of the card slot structure, the lower mold body 3 and the upper mold body 4 can be flexibly replaced;

[0055] During operation, the sliding base plate 2 can use its upper end slot structure to complete the installation and fixation of the lower mold body 3. Secondly, the use of the strip slot 16 in conjunction with the docking card strip 5 can realize the splicing and fixation between the upper mold body 4 and the rotating cylinder 6. Several groups of upper mold bodies 4 and lower mold bodies 3 can be installed on the rotating cylinder 6 and the sliding base plate 2. The flexible replacement of the upper mold body 4 and the lower mold body 3 can improve the flexibility of the CNC bending equipment during use.
